A lithophytic Tillandsia species from the vicinity of El Tule, Oaxaca, Mexico at about 5,300 feet of altitude. Considered a distinct variety of the Tillandsia mitlaensis from near the same area. That form is more of a fasciculate, stemless lithophyte while the variety tulensis is distinctly caulescent. The leaves narrower and smaller than the typical species, with appressed silvery-white scales as opposed to dense pruinose scales of the typical form.

The inflorescence is simple, erect, about six inches long with pink bracts and tubular purple flowers. Easy to grow under typical Tillandsia cultural conditions.

A species with long very thin, grassy leaves, that are stiff, succulent and form a spreading, funnelform rosette. Closely resembling Tillandsia hammeri, it differs in being larger, more spreading, less silvery and stoloniferous. The inflorescence has more and wider branches but is more compact and taller, among other differences. Native to limestone outcrops near Nizanda, Oaxaca, Mexico, it was first collected by Ehlers and only described in 2016. The many leaves form an upright rosette to nearly two feet tall with an erect inflorescence of pink bracts and deep violet flowers.

A caulescent species with a stem to over two feet long with very stiff, thick, spreading, almost succulent, red leaves. The inflorescence consists of a rose-red scape with 3 to 6 narrow, silvery branches, the whole extending over a foot. Native to Veracruz, Mexico where it grows as an epiphyte in small trees under semi-arid conditions. Easy to cultivate.

This is an interesting plant that was first found and collected by Tropiflora's, Dennis Cathcart, on a 1993 expedition. The habitat is the geologically incredible ‘Valle de la Luna’ outside of La Paz, Bolivia. An area of highly eroded hard clay and sandstone that resembles, to some, the surface of the moon. There are thousands of pinnacles and steep cliffs. The occasional shelf holds many species of cacti and at least one Tillandsia; Til. prolata. The plants grow in huge clusters of thousands of plants. All are connected and form long, caulescent stems with short, broadly triangular leaves, covered with silvery trichomes. Roots may or may not form. The inflorescence is a simple spike to about eight inches, with dry, brown bracts and bearing large white, fragrant flowers with spreading petals forming an open corolla.

When first discovered, it was unknown in cultivation, and it was assumed that it would likely not survive at sea level. The habitat is just short of 12,000 feet of altitude with a very dry atmosphere. Harry Luther at the Marie Selby Botanical Gardens described the plant as Tillandsia xiphioides ssp. Prolata after flowering it in cultivation in 1995. Since then it was elevated to a full species; prolata, by Gouda and Barfuss in 2015.

For best results, grow bright and on the dry side. Otherwise the culture is like that of many other high altitude, dry growing Tillandsias which seem to thrive in almost any conditions.
